Is it correct to use a refractive index of 0.25 for Cu when I'm analysing Cu nanopowder dispersions by dynamic light scattering?

The Malvern sample dispersion and refractive index guide states that the RI of copper is 0.25. Is this the correct value to use if I want to model copper nanopowder dispersions in methanol? I'm...
